dear guixers,

i have a custom shepherd action that calls tar with (system ...):

https://github.com/attila-lendvai/guix-crypto/blob/staging/src/guix-crypto/=
services/swarm.scm#L311

it works fine in a `guix system vm` environment, where i'm usually testing =
it. but when i pull it to my server, it fails with exit code 127.

it has logging:

2023-10-30T14:24:12 Will run backup cmd: "install --mode=3D600 <(/gnu/store=
/iiyf5ns10j8sgzfpmcgbfyb0byk5sbjl-tar-1.34/bin/tar --verbose --create --dir=
ectory /var/lib/swarm/mainnet/bee-0 keys/ statestore/ | /gnu/store/gjsxzcc0=
gqpz4lpbsrbidlnn5ij1lfm1-gzip-1.12/bin/gzip) /tmp/2023-10-30-serlap-bee-mai=
nnet-0.tgz", PATH is /gnu/store/d4rqw481nwvrzs09nd8ad647nczgm9k1-coreutils-=
9.1/bin:/gnu/store/gjsxzcc0gqpz4lpbsrbidlnn5ij1lfm1-gzip-1.12/bin, uid is 0
2023-10-30T14:24:12 Cmd returned exit code 127

if i copy-paste the above command into the same root prompt from where i'm =
invoking `herd backup-identity bee-0 /tmp/`, then it works as expected. eve=
n if i prefix it with `PATH=3D"" ...`.

my question is:

what could be the difference between running a `guix system vm` from my git=
 checkout, and guix pull'ing the same to a proper guix system?

could it be file or other permissions? according to the log, (getuid) is 0 =
when the action is executed.

alternatively, how could i debug this?

for completeness, this is how i start the system vm test:

$(./pre-inst-env guix system --no-graphic vm --share=3D$HOME/workspace/guix=
/var-lib-of-guest-vm=3D/var/lib ~/workspace/guix/guix-crypto/tests/swarm-te=
sts.scm) -m 2048

and this is the file:
