Bug ID: 253048
Summary: unionfs shows old file with link count of zero
Product: Base System
Version: 12.2-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: b...@freebsd.org
Reporter: j...@transactionware.com
After executing pwd_mkdb on a system with a unionfs mount above /etc, the
/etc/spwd.db file is the old version of the file with a link count of zero.
Filesystems:
/dev/gpt/root1 on / (ufs, local, read-only)
/dev/gpt/cfg on /cfg (ufs, local, synchronous, soft-updates)
<above>:/cfg/etc on /etc (unionfs, local, read-only)
Command:
pwd_mkdb -p -d /cfg/etc /cfg/etc/master.passwd
Results:
$ ls -il /etc/*pwd.db
65721 -rw-r--r-- 1 root wheel 40960 27 Jan 16:32 /etc/pwd.db
65720 -rw------- 0 root wheel 40960 26 Jan 14:04 /etc/spwd.db
$ ls -il /cfg/etc/*pwd.db
65721 -rw-r--r-- 1 root wheel 40960 27 Jan 16:32 /cfg/etc/pwd.db
65724 -rw------- 1 root wheel 40960 27 Jan 16:32 /cfg/etc/spwd.db
The /etc/spwd.db file with inode number 65720, and a link count of zero, is
identical to the /cfg/etc/spwd.db file from before the pwd_mkdb command
(checked against a backup).
Removing /cfg/etc/spwd.db removes the file from /cfg/etc/spwd.db, but the
/etc/spwd.db version does not change.
