Bug ID: 9826
Summary: post-build scritp - symlinks created in post-build
script are overwritten after exit of the script
Product: buildroot
Version: 2017.02
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
Assignee: unassigned at buildroot.uclibc.org
Reporter: timo.valimaki at sensoan.com
CC: buildroot at uclibc.org
Target Milestone: ---
I'm trying to symlink /etc/group, /etc/passwd and /etc/shadow to RW partition,
in my case to /data/etc (rootfs-overlay).
I created a post-build that moves above files to /data/etc/ directory and
creates symlinks pointing to the moved files. When I'm pausing my post-build
script just before the exit everything is looking fine.
/output/target:
lrwxrwxrwx 1 timo timo 17 huhti 20 12:24 group -> ../data/etc/group
lrwxrwxrwx 1 timo timo 18 huhti 20 12:24 passwd -> ../data/etc/passwd
lrwxrwxrwx 1 timo timo 18 huhti 20 12:24 shadow -> ../data/etc/shadow
But when the Buildroot build is finished the above symlinks are overwritten
-rw-r--r-- 1 timo timo 320 huhti 20 12:29 group
-rw-r--r-- 1 timo timo 389 huhti 20 12:29 passwd
-rw------- 1 timo timo 291 huhti 20 12:29 shadow
Q: Is this as specified or a bug?
Q: If as specified, what is correct way to symlink above files?

Timo,
This is (somewhat) expected. When creating the filsystem images,
there is a part creating the passwd, groups and shadow (and possibly,
gshadow) files from the setting in Buildroot.
This will forcibly create files (AFAIR).
So, what you want to provide is probably a "fakeroot" script. This
will be called after the passwd, group and shadow files are created,
but before the images are assembled.

Thanks.
I have totally missed the fakeroot script - perhaps I have just skipped it as
didn't understood when to use it.
I moved /etc/group, /etc/passwd and /etc/shadow handling from post-build script
to fakeroot script. Result: works as it should be.
I mark bug resolved as invalid.
