 |
|
Hello,
until recently there was no problem with readonly /USR. When I try to update @world now, I get
| Code: | $> sudo etc-update
Scanning Configuration files...
etc-update: ERROR: Need write access to /usr/share/config |
Why is that? Doesn't configuration belong into /etc ?
I think that using links (ln -s /etc/share/config /usr/share/config) as a workaround might cause trouble - sooner or later.

interesting... is that a gentoo specific file? it might need to be moved to /var (variable)

For what it's worth, I have no /usr/share/config directory, but /usr/share/nano contains a handful of files that are ostensibly "configuration." I have in the past made minor changes to some of those files, which causes them to appear to etc-update when nano is rebuilt or updated.
I have no objection to this behavior, just pointing it out. |

You should also play well the "shared" game.
If your host is using something from /usr than it's upto your server that provide the /usr part to be update to provide latest version of what is need in /usr.
As soon as your server is update the /usr/share/config should match yours and etc-update have no reason to complains as the files are the same. |

My apologies for the late reply!
Somehow - when I click "topics started by me" (or however it's called in English) - I always get exactly one "owned" topic … and it is not this one … nor mine at all.
EDIT: Posting here brings this thread back on my "my threads" list. Is this the result of the move of forums.gentoo.org some time ago?
@Naib: +1
@Krinn: I don't know if I understood. If I did: this is a desktop machine running X. There is no server serving binaries or syncing directories.
However, when I run the following to query for write-locked files | Code: | $> sudo lsof +D /usr/ | awk 'NR==1 || $4~/[0-9][uw]/'
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
$> lsof +D /usr | awk 'NR==1 || $4~/[0-9][w]/'
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
$> |
there is no output
but there are many to be deleted files
| Code: | $> sudo lsof /usr | grep -i del | wc -l
2940
$> |
among those - apart from lib* and (s)bin - there are many files in /usr/share/[fonts,icons,mime,locale]. Is it likely that marked-for-deletion is a result of executing emerge @world?
If not, I'm tempted to create a softlink like ln -s /usr/share /var/usr/share. Is there anything strongly speaking against this?
EDIT: ln -s /var/usr/share /usr/share would be correct.
And maybe it is a good idea to execute emerge @world once a week instead of each day, in single mode.

| Don't know if the original post is still relevant, but dispatch-conf is an alternative to etc-update that may not have the same problem. They both come with portage. |

No, it isn't. I just remounted /usr rw… :-\
Interesting, I will see if dispatch-conf handles this differently when it occurs again. |
