 |
|
Hi folks,
Gentoo_amd64
I need to update all running packages to their latest version, if available on Internet. Performed following steps;
# emerge --sync
# emerge --update world
then update config files if necessary.
Please advise whether any further step is necessary thereafter.
If I expect to clear all empty files on the box which will take up space, which command shall I run. How can I ascertain whether they are needed there. TIA
B.R.

I always prefer to update 'system' first then 'world', its mainly for me though. I like to keep my updates as specific as possible.
| Code: | emerge -upv system
emerge -upv world |
always do a pretend (-p) run before the actual emerge, this allows you to verify that the correct USE flags are being picked up (if not add a line to /etc/portage/package.use) and whether or not I feel updating at all is justified.
some people may advocate using the -D emerge command argument, I don't. I rarely use it and my system remains stable and I have very few headaches from routine updates.
I don't have a good answer for your second question, "removing unwanted files".
But it is easy to use portage to see what package a specific file belongs to, using this you can determine whether or not it can be deleted.

I just do world and don't ever seem to have issues, portage gets it right.

Good advice.

I have used -uD weekly and no issues due to this for at least a year.

Search the forums on cruft. I believe there is a script for doing that, although I haven't used it. |

Hi jonnevers,
Tks for your advice.
| Quote: | | always do a pretend (-p) run before the actual emerge, this allows you to verify that the correct USE flags are being picked up (if not add a line to /etc/portage/package.use) |
Which line shall I add?
$ cat /etc/portage/package.use | Code: |
X11-libs/cairo X
x11-libs/cairo x
x11-libs/cairo x
x11-libs/cairo png
|
Shall I run;
# emerge gentookit
# emerge --depclean
# revdep-rebuild
???
TIA
Others noted with tks.

Remove the duplicate lines. They'll just cause possible issues later.

no.
I would recommend you read man emerge first and than search for cruft like I mentioned.

Is there any difference between "cairo X" and "cairo x"? Which one shall I remove? Tks.

depclean is dangerous.
u can save space of /var/tmp/portage/ by dleting it
do not remove any files from installation
the emerge cleans the packages after every emerge it is enough and safe.
if u want u can reamove the /usr/portage/distfiles/ but any update downdate u will have to download all necessary files again.

"portage" is a directory.
$ ls -l /var/tmp/portage/ | Code: |
total 4
drwxrwxr-x 4 root portage 4096 Sep 11 14:36 check-0.9.3-r1 |
Whether you meant deleting the above file?

For /etc/portage/package.use, you want (for your examples given): x11-libs/cairo X png, in order to put them all in one line. There is no 'x' USE-flag, AFAIK (not on Gentoo right now to check); you want 'X'. Also, "X11-libs/cairo" doesn't exist. Portage is case-sensitive, so you have to say "x11-libs". You can combine multiple flags onto one line, like in my example.

Hi Cinder6,

adjusted as advised. Tks
$ cat /etc/portage/package.use | Code: |
x11-libs/cairo X png
|
I suppose /package.mask meant /package.use
Tks
