Seems like your update-initramfs is running under TMPDIR=/tmp/user/0, is
is perhaps mounted with the ‘noexec’ flag set?
That would cause `test -x` to fail on an existing path with the exec bit
set, and per mkinitramfs(8) this not supported:
ENVIRONMENT
mkinitramfs honours the TMPDIR environment variable. If set, it
uses subdirectories in the given directory to create its
temporary working directories. Else it uses /var/tmp as default
value for that purpose. The given directory should be on a
filesystem which allows the execution of files stored there, i.e.
should not be mounted with the noexec mount option.
