Estou executando um script de backup de uma regra do udev. O script monta e copia dados para uma unidade USB recém-conectada, com a ajuda do rsync.
# Mounting stuff
MOUNTPOINT=/media/backup
export OUTPUT=/tmp/rsync-output.log
# -a does not work on exFAT partitions, because of permissions, groups, owner. Use -rltD instead of -rlptgoD, which -a would imply.
rsync -rltDv --exclude '*.app' --exclude-from=/home/gauthier/rsync-exclude.txt /home/gauthier/ $MOUNTPOINT/gauthier/ > $OUTPUT 2>&1
touch /home/gauthier/tmp/I_came_here
rsynccomeça, como mostrado por /tmp/rsync-output.log:

rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1183) [sender=3.1.1]
mas o arquivo /home/gauthier/tmp/I_came_hereque deveria ser criado touchnão está lá. Há outras coisas depois do touch, que também não parecem ser executadas.
Não rsyncdeveria retornar, apesar dos erros? O que poderia fazer com que ele não voltasse?
Eu tentei executar o script a partir do prompt do bash (em vez de deixar a regra do udev executá-lo) e, em seguida, ele parece prosseguir e continuar depois rsync.
