## RHCOS ISO Mount
```bash
# Mount RHCOS ISO from subdirectory
sudo mount -o loop ./rhcos/rhcos-416.94.202410211619-0-live.s390x.iso ~/mnt/rhcos
```

## RHEL ISO Mount
```bash
# Mount RHEL ISO from subdirectory
sudo mount -o loop ./rhel/rhel-9.5-s390x-boot.iso ~/mnt/rhel
```

## Working with ISO Content in Read-Write Mode
ISO9660 filesystems are inherently read-only. To work with the content in a read-write manner:

### Option 1: Extract and Work with Content
```bash
# For RHCOS
mkdir -p ~/rw-rhcos
cp -r ~/mnt/rhcos/* ~/rw-rhcos/
# Now modify content in ~/rw-rhcos/

# For RHEL
mkdir -p ~/rw-rhel
cp -r ~/mnt/rhel/* ~/rw-rhel/
# Now modify content in ~/rw-rhel/
```

### Option 2: Use OverlayFS (Advanced)
```bash
# For RHCOS
mkdir -p ~/overlay-rhcos/{lower,upper,work,merged}
sudo mount -o loop ./rhcos/rhcos-416.94.202410211619-0-live.s390x.iso ~/overlay-rhcos/lower
sudo mount -t overlay -o lowerdir=~/overlay-rhcos/lower,upperdir=~/overlay-rhcos/upper,workdir=~/overlay-rhcos/work overlay ~/overlay-rhcos/merged
# Now you can modify files in ~/overlay-rhcos/merged and changes will be stored in ~/overlay-rhcos/upper
```

### Option 3: Create a New ISO After Modifications
```bash
# After making changes in the extracted directory, create a new ISO:
sudo genisoimage -o new-rhcos.iso -r -J -V "RHCOS_NEW" ~/rw-rhcos/
```

## Unmount Commands
When you're done using the ISOs, unmount them with:
```bash
sudo umount ~/mnt/rhcos
sudo umount ~/mnt/rhel
```
