Public bug reported: Is there a way to prevent systemd from creating generator targets for hot-plug disks?
Currently it is causing very long delays at boot-time - which are not interruptible by the sys-admin - but I'm not sure at what point systemd decided those hot-plug devices should be added to the boot-time tasks, or how to safely delete them. There are generator rules added at some stage but I cannot find information on how to safely remove them, or how to prevent them being created. In this output the device-mapper names prefixed LUKS_HDD_ are the problem: $ ls -l /var/run/systemd/generator/* -rw-r--r-- 1 root root 486 Sep 2 11:45 /var/run/systemd/generator/boot.mount -rw-r--r-- 1 root root 486 Sep 2 11:45 /var/run/systemd/generator/home.mount -rw-r--r-- 1 root root 294 Sep 2 11:45 /var/run/systemd/generator/-.mount -rw-r--r-- 1 root root 933 Sep 2 11:45 /var/run/systemd/generator/systemd-cryptsetup@LUKS_BOOT.service -rw-r--r-- 1 root root 933 Sep 2 11:45 /var/run/systemd/generator/systemd-cryptsetup@LUKS_DATA.service -rw-r--r-- 1 root root 887 Sep 2 11:45 /var/run/systemd/generator/systemd-cryptsetup@LUKS_HDD_OS.service -rw-r--r-- 1 root root 887 Sep 2 11:45 /var/run/systemd/generator/systemd-cryptsetup@LUKS_HDD_VM.service -rw-r--r-- 1 root root 929 Sep 2 11:45 /var/run/systemd/generator/systemd-cryptsetup@LUKS_OS.service -rw-r--r-- 1 root root 491 Sep 2 11:45 /var/run/systemd/generator/usr-local.mount -rw-r--r-- 1 root root 485 Sep 2 11:45 /var/run/systemd/generator/var.mount ** Affects: systemd (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1491393 Title: 15.10: Long boot-time delays trying to find disconnected hot-plugged storage devices Status in systemd package in Ubuntu: New Bug description: Is there a way to prevent systemd from creating generator targets for hot-plug disks?
