На сервере в ветке, из которой была установлена ОС в ostree [подробнее об установке](alt_on_ostree.md), создать новый коммит. Для этого внести изменения в каталог root и вызвать ostree commit без параметра --parent=none. Указать версию. Например так:
```
touch root/usr/bin/privet
chmod a+x root/usr/bin/privet
echo "echo Privet" > root/usr/bin/privet
sudo ostree commit --repo=repo --tree=dir=root -b alt/x86_64/coreos/stable --owner-uid 0 --owner-gid 0 --no-xattrs --no-bindings --mode-ro-executables --add-metadata-string=version=sisyphus.`date +%Y%m%d`.0.1
sudo touch root/usr/bin/privet
sudo chmod a+x root/usr/bin/privet
echo "echo Privet"|sudo tee root/usr/bin/privet
sudo ostree commit --repo=repo --tree=dir=root -b alt/x86_64/coreos/stable --no-xattrs --no-bindings --mode-ro-executables --add-metadata-string=version=sisyphus.`date +%Y%m%d`.0.1
```
Результат можно будет проверить следующими командами:
