I can normaly mount/umount FTP as file system using following commands:
└──> curlftpfs -o codepage=windows-1250 anonymous:[email protected] /home/marek/ftpfs
└──> ls /home/marek/ftpfs/
1 2 3
└──> fusermount -u /home/marek/ftpfs
└──> ls /home/marek/ftpfs/
└──>
But when I issue curlftpfs with strace then nothing is mounted and the process exits with status 1:
└──> strace -f curlftpfs -o codepage=windows-1250 anonymous:[email protected] /home/marek/ftpfs
└──> echo $0
1
└──> ls /home/marek/ftpfs/
└──>
