Function sys_pkg_remove 

pub fn sys_pkg_remove(_name: &str) -> SyscallResult<()>

Remove an installed package from the system.

Performs a transactional package removal. Configuration files installed by the package are preserved by default (saved with a .veridian-save suffix) so the user does not lose customizations. After removal, the package manager checks for orphaned dependencies (packages that were installed only as dependencies of the removed package and are no longer required) and offers to remove them.

The removal process follows these steps:

1. Verify the package is installed and not required by other packages.
2. Run pre-removal hooks if defined in the package manifest.
3. Remove installed files from the VFS (preserving config files).
4. Update the package database to mark the package as removed.
5. Detect and optionally clean up orphaned dependencies.
6. Run post-removal hooks if defined.

Arguments

• name - Name of the installed package to remove.

Returns

• Ok(()) on successful removal of the package.

Errors

• SyscallError::NotFound - The package is not currently installed.
• SyscallError::PermissionDenied - The caller lacks the package management capability.
• SyscallError::InvalidArgument - The package name is empty or contains invalid characters.
• SyscallError::NotSupported - The package is a critical system package that cannot be removed, or other installed packages depend on it and --force was not specified.
• SyscallError::IoError - A disk I/O error occurred during file removal.

Examples

use veridian_kernel::pkg::sdk::syscall_api::sys_pkg_remove;

// Remove a package (config files are preserved)
sys_pkg_remove("libfoo").expect("remove failed");
