Bug 127897 – portage should not unlink /etc/profile.env before overwriting it

• Status: RESOLVED FIXED
• Product: Portage Development

[Description Patrick McLean 2006-03-28 12:19:36 UTC]

Currently, portage unlinks /etc/profile.env before recreating it, if /etc/profile.env happens to be a symlink, the symlink will be removed and replaced with a regular file.

This is a huge pain for a diskless system that uses symlinks in /etc for files that need to be writeable on the nodes.

If not unlinking is not feasable, portage could resolve the symlink before writing the file.

Thanks for the patch.  This should go in 2.1_pre7-r3.

I've added a fix in r3034 so that symlinks are automatically followed inside atomic_ofstream. If an error occurs opening the file, it will fall back and try again (without following the symlink).

Released in 2.1_pre7-r3.
