Command to work with entries in /etc/filesystems

In AIX there are a lot of small nice commands to make changes to /etc/hosts, /etc/resolv.conf, /etc/security/user, /etc/inittab, etc. but there are no commands to add/change/remove entries in /etc/filesystems without changing logical volumes.

It would be nice to have commands to add entry into /etc/filesystems, change and remove it.

The current commands such as mkfs/crfs create not only entry in /etc/filesystems, but also a file system on a device. The command rmfs works the same way - removes the entry in /etc/filesystems and the corresponding logical volume.

    imfs -x -l oraclelv ### Removes the filesystem entry referenced by oraclelv
    imfs -l oraclelv ### Adds the filesystem entry referenced by oraclelv based on LVM info.

    imfs -x datavg ### removes all of them for datavg
    imfs datavg ### Adds all of them for datavg

    What specifically is missing?

    Besides mkfs/crfs/rmfs, AIX has:
    chfs - changes entries in /etc/filesystems

    imfs - adds and removes /etc/filesystems entries based on LVODM

    mknfs - adds NFS to /etc/filesystems (and rmnfs)

    mkcifsmnt / mkcifscred (and rm/ch varieties)

    RAMFS, UDF and CDRFS are not really appropriate for /etc/filesystems.
