Package: os-prober Severity: normal Dear Maintainer,
Ploop is a block device used by OpenVZ / Virtuozzo containers: https://wiki.openvz.org/Ploop https://manpages.ubuntu.com/manpages/xenial/man8/ploop.8.html Currently on a system with running containers, os-prober checks their ploop devices and thus analyzes OSes inside them. e.g: ... Found CentOS Linux release 7.7.1908 (Core) on /dev/ploop12024p1 ... However, this has nothing to do with the main system and such entries should not go tothe host grub menu. Moreover, such a scan slows down os-prober work if we have many containers on the system. This can be easily fixed by a patch like the following:2 diff --git a/os-prober b/os-prober index ccfdf13..8e69c56 100755 --- a/os-prober +++ b/os-prober @@ -37,6 +37,10 @@ partitions () { # Exclude partitions on physical disks that are part of a # Serial ATA RAID disk. for part in /sys/block/*/*[0-9]; do + if [ "${part:0:16}" = "/sys/block/ploop" ]; then + # Skipping ploop devices + continue + fi if [ -f "$part/start" ] && \ [ ! -f "$part/whole_disk" ] && ! on_sataraid $part; then name="$(echo "${part##*/}" | sed 's,[!.],/,g')" -- System Information: Debian Release: 8.11 Architecture: amd64 (x86_64) Kernel: Linux 3.16.0 (SMP w/48 CPU cores) Locale: LANG=C, LC_CTYPE=C (charmap=ANSI_X3.4-1968) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system)
