## Update
|
|
|
|
To eliminate most of the question in IRC (#pentoo) and to start a good documentation process, here are the steps to bring your system up to date.
|
|
|
|
**WARNING**: The errors on your screen need to be read and acted upon, following these directions blindly will result in failure, then ridicule, then more failure.
|
|
|
|
### For the first time
|
|
|
|
##### Sync with the portage tree
|
|
````
|
|
emerge --sync
|
|
````
|
|
##### Modify /etc/portage/make.conf file for your system:
|
|
|
|
Please adjust your CFLAGS as desired, information can be found here: https://wiki.gentoo.org/wiki/CFLAGS
|
|
Do not modify these FLAGS unless you know what you are doing, always check the defaults first with:
|
|
````
|
|
portageq envvar CFLAGS
|
|
````
|
|
This is the default for pentoo at the time of build:
|
|
````
|
|
# CFLAGS="-Os -mtune=nocona -pipe -ggdb"
|
|
````
|
|
A safe choice would be to keep whatever Pentoo defaults are, but optimize for your specific machine:
|
|
````
|
|
CFLAGS="${CFLAGS} -march=native"
|
|
CXXFLAGS="${CFLAGS}"
|
|
FCFLAGS="${CFLAGS}"
|
|
FFLAGS="${CFLAGS}"
|
|
````
|
|
MAKEOPTS is set automatically by the profile to jobs equal to processors, you do not need to set it.
|
|
````
|
|
ACCEPT_LICENSE="Oracle-BCLA-JavaSE NVIDIA-CUDA google-chrome Google-TOS PUEL baudline"
|
|
````
|
|
You may wish to edit your VIDEO_CARDS line to match your system better.
|
|
Example, for nvidia/ati users should add nvdia/fglrx flags:
|
|
````
|
|
VIDEO_CARDS="fbdev vga vesa nvidia"
|
|
````
|
|
Guest OS users should add virtualbox/vmware or qxl flag(s):
|
|
````
|
|
VIDEO_CARDS="fbdev vga vesa virtualbox"
|
|
````
|
|
##### Modify your profile only if you know what you are doing, default should be fine for most users
|
|
````
|
|
eselect profile list
|
|
eselect profile set <number>
|
|
````
|
|
*Follow the pentoo-updater below*
|
|
### On regular basis
|
|
Pay extra attention on upgrading kernel, gcc, python or any other system package. It is important to upgrade these packages properly before moving to the next step. You might also need to understand Upgrading Gentoo generic guideline.
|
|
|
|
Very recently some changes were pushed to Pentoo which moved the Pentoo Overlay from /var/lib/layman to /var/db/repos so:
|
|
|
|
##### If you have /var/db/repos/pentoo:
|
|
|
|
````
|
|
cd /var/db/repos/pentoo
|
|
git pull
|
|
./scripts/pentoo-updater.sh
|
|
````
|
|
|
|
everything should work now,
|
|
|
|
|
|
##### If you have /var/lib/layman/pentoo:
|
|
|
|
````
|
|
cd /var/lib/layman/pentoo
|
|
git pull
|
|
./scripts/pentoo-updater.sh
|
|
````
|
|
|
|
everything should work now,
|
|
|
|
|
|
##### This syncs the gentoo and pentoo repos like "apt-get update" in debian
|
|
````
|
|
emerge --sync
|
|
````
|
|
##### This updates all the normal packages like "apt-get upgrade" in debian
|
|
````
|
|
emerge --deep --update --newuse world -vt
|
|
````
|
|
##### This optionally merges in changed config files. unchanged files are merged automatically
|
|
````
|
|
etc-update
|
|
````
|
|
##### This removes old packages which are not needed like "apt-get autoremove" in debian
|
|
````
|
|
emerge --depclean
|
|
````
|
|
##### This rebuilds anything which may have been broken in update
|
|
````
|
|
emerge @preserved-rebuild
|
|
````
|
|
##### This checks all the programs installed from VCS for new revisions and updates if needed
|
|
````
|
|
smart-live-rebuild
|
|
````
|
|
##### Verifies there is no breakage after updates
|
|
````
|
|
revdep-rebuild
|
|
````
|
|
##### merge in any new config files
|
|
````
|
|
etc-update
|
|
````
|
|
##### clean up the distfiles/packages dirs to remove old/un-needed files
|
|
````
|
|
eclean-dist -d && eclean-pkg -d
|
|
````
|
|
*Check /var/log/portage/elog/summary.log file*
|
|
|
|
##### Kernel update
|
|
Follow the usual Gentoo way. Once the source is installed, download the latest config and run:
|
|
````
|
|
genkernel --no-clean --luks --gpg all
|
|
emerge @module-rebuild
|
|
````
|
|
and add a new boot menu in the /boot/grub/menu.lst file
|
|
|
|
##### You might need to run extra commands. For example:
|
|
````
|
|
emerge @x11-module-rebuild
|
|
eselect java-vm set system icedtea-bin-7
|
|
````
|
|
after python/perl upgrade:
|
|
````
|
|
perl-cleaner --modules
|
|
python-updater
|
|
````
|
|
|
|
*Run the following command under each regular user's account*
|
|
##### Regenerate the main menu for XFCE WM (or "-e" for e17, "-k" for KDE)
|
|
````
|
|
genmenu.py -x
|
|
````
|
