Public bug reported:
This error is received for each LVM listed in the rsnapshot.conf file:
Use of uninitialized value $linux_lvm_oldpwd in concatenation (.) or
string at /usr/bin/rsnapshot line 3720.
chdir()
Use of uninitialized value $linux_lvm_oldpwd in chdir at
/usr/bin/rsnapshot line 3722.
Use of chdir('') or chdir(undef) as chdir() is deprecated at
/usr/bin/rsnapshot line 3722.
The error actually occurs at the assignment of $linux_lvm_oldpwd on line 3543.
$linux_lvm_oldpwd = $ENV{PWD};
$ENV{PWD} returns nothing. This was not the case in December and this
started failing for me sometime around Jan 10th, 2014. I am not a Perl
programmer but the documentation I found states that the proper way to
get the current working directory is to call cwd() and NOT use
$ENV{PWD}.
I replaced the offending line with the following:
$linux_lvm_oldpwd = cwd();
I no longer experience the issue.
