Mount Windows Share on Linux/RHEL

• 1 dnf install samba-client cifs-utils
  # samba (server) is not needed if you only mount SMB shares
  
• 2 One-Liner:
  sudo mount -t cifs -o username=<WinUser>,domain=<GRP>,uid=1000,gid=1000,dir_mode=0755,file_mode=644,iocharset=utf8,serverino,noatime //1.2.3.4/devshare /mnt/devshare
  
• 3 Permanent mount in /etc/fstab:
  //1.2.3.4/devshare /mnt/devshare cifs credentials=/etc/samba/creds/devshare-rw.cred,uid=1000,gid=1000,dir_mode=0755,file_mode=0644,iocharset=utf8,_netdev,x-systemd.automount,serverino,noatime,nofail 0 0
  Credentials file:
  vim /etc/samba/creds/devshare-rw.cred
  username=DevShareWriter
  password=1234
  domain=DOMAIN # optional
  chmod 700 /etc/samba/creds
  chmod 600 /etc/samba/creds/devshare-rw.cred
  
• 4 reboot
  ls -la /run/systemd/generator/mnt-*
  ls /mnt/devshare # Automounts
  systemctl status mnt-devshare.mount
  
• N _netdev waits for network
  x-systemd.automount converts the mount into on-demand automount unit
  serverino stable inodes for git, rsync
  noatime no file access time
  More info: man mount.cifs
