LABEL persists while looping past GPT disks
When a disk is encountered which has no partition scheme, a diskid/DISK-* label is shown properly,
but on the next disk with GPT partitions the raw disk shows the label from the prior disk.
I have not tested with other types than GPT.
da3 0:138 373G - diskid/DISK-0QY4XMRA -
da4 0:201 186G GPT diskid/DISK-0QY4XMRA -
da4p1 0:251 512K freebsd-boot gpt/gptboot2 -
<FREE> -:- 492K - - -
I believe under __gpart_present() you simply need to blank the label variable as done with some other fields. After adding local LABEL="-" I see more the output I expected.

Wrong fstype detected for ZFS RAID-Z1
On FreeBSD 13.0 / amd64, I have 4 SATA disks (ada0, ada1, ada2, ada3) used in a ZFS RAID-Z1 filesystem :
$ sysctl kern.disks
kern.disks: ada5 ada4 ada3 ada2 ada1 ada0
$ zpool list -v
NAME SIZE ALLOC FREE CKPOINT EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT
tank 5.44T 2.78T 2.66T - - - 51% 1.00x ONLINE -

With your script lsblk, the FS type for the 4 disks/partitions is not detected properly, apple-zfs instead of freebsd-zfs :
./lsblk ada0
DEVICE MAJ:MIN SIZE TYPE LABEL MOUNT
ada0 0:116 1.4T GPT - -
<FREE> -:- 111K - - -
ada0p1 0:117 1.4T apple-zfs gpt/zfs -
ada0p9 0:118 8.0M solaris-reserved
Device path is incompatible with linux
In the Linux implementation, you need to specify the path to the device.
$ lsblk sda
lsblk: sda: not a block device
$ lsblk /dev/sda
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 223,6G 0 disk
├─sda1 8:1 0 512M 0 part /boot/efi
└─sda2 8:2 0 223,1G 0 part /
In your implementation, specifying the /dev/ directory results in an error.
# lsblk ada0
DEVICE MAJ:MIN SIZE TYPE LABEL MOUNT
ada0 0:106 932G GPT - -
ada0p1 0:108 512K freebsd-boot - -
<FREE> -:- 492K - - -
ada0p2 0:110 932G freebsd-zfs - <ZFS>
<FREE> -:- 676K - - -
# lsblk /dev/ada0
NOPE: disk '/dev/ada0' does not exist in the system
Because of this, it is difficult to use lsblk in scripts running under both Linux and FreeBSD
--json option isn't supported
The rpi-imager expects the --json option here but it isn't supported.
fstat: /dev/fuse: No such file or directory
Hi!
I've just upgraded to 3.6 and I'm getting the following error:
# lsblk
DEVICE MAJ:MIN SIZE TYPE LABEL MOUNT
ada0 0:101 233G GPT - -
fstat: /dev/fuse: No such file or directory
ada0p1 0:102 512K freebsd-boot gpt/gptboot0 -

ada0p3 0:104 222G freebsd-zfs gpt/zfs0 <ZFS>
<FREE> -:- 9.3G - - -
This is caused by an unconditional use of /dev/fuse at https://github.com/vermaden/lsblk/blob/master/lsblk#L281
FreeBSD-12.2-STABLE with up-to-date ports collection.
Cheers,

lsblk handling of spaces in GEOM labels
Hi, thanks for lsblk!
AFAIK spaces are allowed in GEOM labels; at least I haven't seen anything that prohibits it.
Kind regards,
Eric
