Program mount doesn't accept longer list of the parameters.
example:
mount -t overlay -o
workdir=/mnt/working/base_123456789ABCDEFG/head/lrs/overlayfs_work/local,lowerdir=/mnt/working/base_123456789ABCDEFG/head/lrs/local:/mnt/working/base_123456789ABCDEFG/head/lrs/template:/mnt/working/base_123456789ABCDEFG/head/lrs/crossdev:/mnt/working/base_123456789ABCDEFG/head/lrs/reho:/mnt/working/base_123456789ABCDEFG/head/lrs/stage,rw
none /mnt/working/base_123456789ABCDEFG/head/au/local

Result if fails: (pre_path="123456789ABCDEFGH")
[ failed !]
mount: /mnt/working/base_123456789ABCDEFGHI/head/au/local: wrong fs
type, bad option, bad superblock on none, missing codepage or helper
program, or other error.
dmesg(1) may have more information after failed mount system call.
but it works: (pre_path="123456789ABCDEFG")
example:
mount -t overlay -o

df -h

/mnt/working/base_123456789ABCDEFG/head/au/local
On the previous versions it works fine. (2.40-*)
