5 months ago What distribution are you using? The Snapshots submenu is only supported on RHEL7 and earlier due to changes in the distribution: on RHEL8 and later, as well as Fedora 30 onwards the BootLoader Specification is used by default, which means that the boom-managed boot entries cannot be placed in a separate submenu. Later releases of boom have removed the configuration options, but they are still present in older distribution packages on RHEL8.
I just realised that the README.md still mentions these options - I will get that updated to reflect the current status.
All my snapshot entries are showing up as regular grub items.
I have this in /etc/default/boom: BOOM_USE_SUBMENU="yes" BOOM_SUBMENU_NAME="Snapshots"
And this in /etc/default/grub: GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)" GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=false GRUB_TERMINAL_OUTPUT="console" GRUB_CMDLINE_LINUX="pci=nommconf,bfsort crashkernel=0M-4G:168M,4G-256G:256M,256G-:512M rhgb quiet rd.shell=0 ipv6.disable=1 rd.plymouth=0 rd.lvm.vg=rootvg rd.lvm.lv=rootvg/lv_root rd.lvm.lv=rootvg/lv_swap" GRUB_DISABLE_RECOVERY=true GRUB_DISABLE_OS_PROBER=true GRUB_ENABLE_BLSCFG=true
But still no grub submenu is ever created, just entries in the list.
