Portage update helper commands.
Project description
Easier Gentoo system maintenance
This is a set of commands to simplify maintaining a Gentoo system.
esync
This command needs eix
installed to fully function. It runs eix-sync
. This
is intended for use as a cron job. I use it daily.
This command can run layman -S
for you if you pass -l
or --run-layman
.
emerges
This command will do the following:
- Update Portage
- Update
@world
with options--with-bdeps=y
,--update
,--deep
,--newuse
- Update live installations of packages (
@live-rebuild
) - Run
emerge @preserved-rebuild
- Run
systemctl daemon-reexec
(if applicable) - Update the kernel
There are flags to disable most parts of this functionality, such as
--no-upgrade-kernel
. Pass --help
to see all the options.
Automatic kernel update process
Older versions of this tool supported various ways to update the kernel to boot from. However this
is better left to the configuration and hooks of kernelinstall
which is invoked by make install
.
The automatic kernel update will only work if there are 2 kernels displayed
with the command eselect --brief kernel list
. The first one in the list must
be the active kernel. The second one is the one to upgrade to. After switching
to the new kernel, a .config
must exist in /usr/src/linux
or the command
will not run make
. If the configuration exists at /proc/config.gz
it will
be used.
If emerges
fails to build the kernel because of the state of
eselect kernel list
, you can fix it and re-run the update by running
upgrade-kernel
.
The old kernel data in /boot
will be stored in /root/.upkeep/old-kernels
.
If you want to only rebuild the kernel, run rebuild-kernel
.
ecleans
This command will run the following commands (or equivalents):
emerge --depclean
emerge @preserved-rebuild
revdep-rebuild
eclean-dist --deep
rm -fR /var/tmp/portage/*
