genfstab with partlabel on gpt partitioned disk?
When using gpt partitioned disk,
genfstab -L /dev/sda >> /mnt/etc/fstab
just uses /dev/sda1, /dev/sda2 etc.
Is there any way to get it to use the partlabels?

Re: genfstab with partlabel on gpt partitioned disk?
Do you actually have labels on the filesystems? Labels are different than partlabels.
The file will also list the /dev/sda1 notation in a comment, but that's nothing.

Re: genfstab with partlabel on gpt partitioned disk?
using
parted -s -- /dev/sda name 1 boot
parted -s -- /dev/sda name 2 root
only gives me partlabels.
I can't remember, but I think on an msdos partitioning scheme, that would give me regular labels that show up under /dev/disk/by-label.
I assume I cannot get those to be replaced by /dev/disk/by-partlabel, so I'm already working on a little Perl script to part blkid and replace each e.g.
/dev/sda1
with
/dev/disk/by-partlabel/boot
etc.
Perhaps I'm missing something though?

Here's my solution... note that this is being run from Ansible in a loop, so the {{ item.1.name }} is replaced with each desired partition.

parted does partlabels
for labels, you have to look to the filesystem. In case of ext234 you can change the label with tune2fs.

Hi:
genfstab -U -p /dev/sda >> /mnt/etc/fstab
-U use UUID , by default genfstab use label.
Cheers

To use PARTLABEL:
# genfstab -t PARTLABEL /mnt >> /mnt/etc/fstabOffline
