Title:
  /usr/share/initramfs-tools/hooks/lvm2 is not executable

Status in lvm2 package in Ubuntu:
  New

Bug description:
  after a recent (yesterday/today) upgrade of hirsute, it could not boot
  from LUKS root, dropping to inirtamfs. Investigation showed that `lvm`
  binary is not present in initramfs generated by initramfs-tools. When
  I ran `initrmfs-tools` by hand with `-v` option, I noticed the
  message:

  /usr/share/initramfs-tools/hooks/lvm2 ignored: not executable

  (this message does not show up when initramfs-tools is run without `-v`)
  Sure enough, after manually changing permissions to all-executable and rerunning initramfs-tools the binary is included in initrd and system boots normally.  But reinstalling lvm2 resets permissions again:

  $ ls -l /usr/share/initramfs-tools/hooks/lvm2 
  -rw-r--r-- 1 root root 691 Feb  8 16:25 /usr/share/initramfs-tools/hooks/lvm2

  and on the next build, initrd does not contain lvm binary again.
