It also appears the `-mkfs-time 0`, `-all-time 0`, and `-UTC` arguments have
been missing.
Docker and Singularity havebeen moving towards support of the Open Containers
Initative, which prompts the discussion of if the docker and sinfularity
(squashfs) pack options should be depricated in favor of this standard:

Subject: Modifying squashfs usage for `guix pack` for supporting singularity
I ran into some trouble today when trying to package an image for singularity
on CentOS7. nxck suggested I go into the cdoe and try adding the "-noappend"
option to mksquashfs in 'guix/guix/scripts/pack.scm'. While looking at it, it
seems that it performs a multistep process to modify the squashfs image, which
kind of goes against the design of the utility. A SO page (
https://unix.stackexchange.com/a/459372 ) suggested the full hierarchy be
created and then added in a single invocation. Does anyone have any opinions
on such a change or useful insights?
